Frequently Asked Questions (FAQ)

Which brand of furnace filters is best?

The brand of furnace filters you want to buy will depend on a couple of factors. Are you looking for a filter that will fit most makes and models of furnaces, or one that has to be custom fitted for your furnace? If the latter, then you’ll want to buy furnace filters from the manufacturer of your furnace.

Another thing to determine is whether you’re looking for a filter that can be cleaned and reused, and whether you’re looking for a filter that’s disposable or one that’s rechargeable. If you want to clean and reuse your filter, then you’ll want to buy furnace filters from a well known brand such as Honeywell or Maytag. If you want to use a disposable filter, you might want to buy a filter from a smaller brand.

What is the best MERV rating for furnace filters?

When looking for a furnace filter, you’ll notice that a lot of them list a MERV rating. MERV is an acronym for the Minimum Efficiency Reporting Value, which is a system used to classify the particle capture effectiveness of a filter. Manufacturers use this to set a baseline of effectiveness for a filter, and the higher the rating, the more particles it can capture. The top one is a 20 and the bottom only a 1.

The higher the MERV rating, the higher the quality, but you can still get a lot of effectiveness from a low-end filter. We recommend a MERV rating of at least 11, since this is a balance between effectiveness and cost. Anything below an 11 would be a really basic and low-quality filter.

Do furnace filters do best?

Furnace air filters are very important because they prevent dust particles and other contaminants from entering your home and influencing your health. They also cut down on the amount of dust that ends up accumulating on your furniture and in your rooms. Investing in air filters, furnace and otherwise, is a must for any homeowner.

An air conditioning/furnace service may recommend that you replace your filters every six months. Check the date you installed them and change them if you haven’t done so already.

Are cheap furnace filters better?

While more expensive furnaces filters will usually last longer than the cheap ones, that might not be the case every single time. That all depends on the brand and quality of the products. Bear in mind that if they’re less expensive, it isn’t just because they’re inexpensive, they’re cheaper because they’re made from inferior materials, or because it’s a knockoff brand.Just be aware that sometimes, a lower price doesn’t make it a better deal.

Conclusion

As you look for a furnace filter make sure to do your research or you might end up with a furnace filter that you’ll need to replace in 6 months. All filters are not made the same, and some work better than others. If you’re replacing your filter with something cheap you’re likely going to find yourself replacing the filter too frequently. Fact is some people don’t realize that there are filtration products built for the job and some made for temporary solutions. There are a few things to consider when choosing the best furnace filter for the job.
